About: Sony WH-RF400 Wireless Home Theater Headphones

The Sony WH-RF400 wireless TV headphones solve this problem, without forcing you to crank up the volume and disturb others. The wireless transmitter connects to your TV's analog RCA audio outputs or headphone jack. (Please note: there are no HDMI, optical, or other digital connection options.)

I've tested an earlier version of this system, and the headset made speech so much easier to follow than my TV's built-in speakers. Plus, I was able to enjoy big movie effects in a place where firing up a surround sound system would be a no-no — namely next to my napping two-year-old's bedroom.

How it works, and what's included

Use one the included cables to connect the WH-RF400's transmitter to your TV or audio system. The transmitter sends an audio signal wirelessly to the included headset. Slip the headset over your ears, and you get clear, powerful — and personal — TV sound.

Easy-to-wear headset with on-ear controls

The headset feels incredibly light, so even though it fits over your ears, it is unobtrusive. You'll appreciate that during longer movies and binge-watching sessions. Controls are convenient, too. There's a volume dial on the right ear cup, and below it a "Voice mode" button that brings the dialogue front and centre.
